2017 FIAT 500L TPMS

As an added safety feature, your vehicle has been
equipped with a Tire Pressure Monitoring System
(TPMS) that illuminates a low tire pressure telltale
when one or more of your tires is significantly under-
inflated. Accordingly, when the low tire pressure telltale
illuminates, you should stop and check your tires as
soon as possible and inflate them to the proper pres-
sure. Driving on a significantly under-inflated tire
causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.
Please note that the TPMS is not a substitute for proper
tire maintenance, and it is the driver ’s responsibility to
maintain correct tire pressure, even if under-inflation
has not reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a TPMS
malfunction indicator to indicate when the system is
not operating properly. The TPMS malfunction indica-
tor is combined with the low tire pressure telltale. When
the system detects a malfunction, the telltale will flash
for approximately one minute and then remain continu-
ously illuminated. This sequence will continue uponsubsequent vehicle start-ups as long as the malfunction
exists. When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire
pressure as intended. TPMS malfunctions may occur for
a variety of reasons, including the installation of re-
placement or alternate tires or wheels on the vehicle
that prevent the TPMS from functioning properly. Al-
ways check the TPMS malfunction telltale after replac-
ing one or more tires or wheels on your vehicle, to
ensure that the replacement or alternate tires and
wheels allow the TPMS to continue to function prop-
erly.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warning have been established for the tire size
equipped on your vehicle. Undesirable system op-
eration or sensor damage may result when using
replacement equipment that is not of the same size,
type, and/or style. Aftermarket wheels can cause
sensor damage. Using aftermarket tire sealants may
cause the Tire Pressure Monitoring System (TPMS)

CYBERSECURITY
Your vehicle may be a connected vehicle and may be
equipped with both wired and wireless networks.
These networks allow your vehicle to send and receive
information. This information allows systems and fea-
tures in your vehicle to function properly.
Your vehicle may be equipped with certain security
features to reduce the risk of unauthorized and unlaw-
ful access to vehicle systems and wireless communica-
tions. Vehicle software technology continues to evolve
over time and FCA US LLC, working with its suppliers,
evaluates and takes appropriate steps as needed. Simi-
lar to a computer or other devices, your vehicle may
require software updates to improve the usability and
performance of your systems or to reduce the potential
risk of unauthorized and unlawful access to your
vehicle systems.
The risk of unauthorized and unlawful access to your
vehicle systems may still exist, even if the most recent

WARNING!
The temperature grade for this tire is established
for a tire that is properly inflated and not over-
loaded. Excessive speed, under-inflation, or exces-
sive loading, either separately or in combination,
can cause heat buildup and possible tire failure.
TIRE PRESSURE MONITORING SYSTEM (TPMS)
The Tire Pressure Monitor System (TPMS) will warn the
driver of a low tire pressure based on the vehicle
recommended cold tire pressure.
The tire pressure will vary with temperature by about 1
psi (7 kPa) for every 12°F (6.5°C). This means that when
the outside temperature decreases, the tire pressure will
decrease. Tire pressure should always be set based on
cold inflation tire pressure. This is defined as the tire
pressure after the vehicle has not been driven for at least
three hours, or driven less than 1 mile (1.6 km) after a
three hour period. The cold tire inflation pressure must
not exceed the maximum inflation pressure molded into
the tire sidewall. Refer to “Tires – General Information”
in “Starting And Operating” for information on how to
properly inflate the vehicle’s tires. The tire pressure willalso increase as the vehicle is driven, this is normal and
there should be no adjustment for this increased pres-
sure.
The TPMS will warn the driver of a low tire pressure if
the tire pressure falls below the low pressure warning
limit for any reason, including low temperature effects,
or natural pressure loss through the tire.
The TPMS will continue to warn the driver of low tire
pressure as long as the condition exists, and will not
turn off until the tire pressure is at or above the
recommended cold tire pressure on the placard. Once
the low tire pressure warning (Tire Pressure Monitoring
Telltale Light) illuminates, you must increase the tire
pressure to the recommended cold tire pressure in order
for the Tire Pressure Monitoring Telltale Light to turn
off. The system will automatically update and the Tire
Pressure Monitoring Telltale Light will turn off once the
system receives the updated tire pressures. The vehicle
may need to be driven for up to 20 minutes above
15 mph (24 km/h) in order for the TPMS to receive this
information.
For example, your vehicle may have a recommended
cold (parked for more than three hours) tire pressure of
30 psi (207 kPa). If the ambient temperature is 68°F
262 STARTING AND OPERATING

(20°C) and the measured tire pressure is 27 psi (186
kPa), a temperature drop to 20°F (-7°C) will decrease
the tire pressure to approximately 23 psi (159 kPa). This
tire pressure is sufficiently low enough to turn on the
Tire Pressure Monitoring Telltale Light. Driving the
vehicle may cause the tire pressure to rise to approxi-
mately 27 psi (186 kPa), but the Tire Pressure Monitor-
ing Telltale Light will still be on. In this situation, the
Tire Pressure Monitoring Telltale Light will turn off only
after the tires are inflated to the vehicle’s recommended
cold tire pressure value.
CAUTION!
•The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures and
warnings have been established for the tire size
equipped on your vehicle. Undesirable system
operation or sensor damage may result when
using replacement equipment that is not of the
same size, type, and/or style. Aftermarket wheels
can cause sensor damage. Using aftermarket tire
sealants may cause the Tire Pressure Monitoring
System (TPMS) sensor to become inoperable.
(Continued)
CAUTION! (Continued)
After using an aftermarket tire sealant it is recom-
mended that you take your vehicle to an autho-
rized dealership to have your sensor function
checked.
• After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the valve
stem, which could damage the Tire Pressure
Monitoring Sensor.
NOTE:
• The TPMS is not intended to replace normal tire care
and maintenance, or to provide warning of a tire
failure or condition.
• The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
• Driving on a significantly under-inflated tire causes
the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire
tread life, and may affect the vehicle’s handling and
stopping ability.

STARTING AND OPERATING 263

•The TPMS is not a substitute for proper tire mainte-
nance, and it is the driver ’s responsibility to maintain
correct tire pressure using an accurate tire gauge,
even if under-inflation has not reached the level to
trigger illumination of the Tire Pressure Monitoring
Telltale Light.
• Seasonal temperature changes will affect tire pres-
sure, and the TPMS will monitor the actual tire
pressure in the tire.
Base System
This is the TPMS warning indicator located in
the instrument cluster.
The TPMS uses wireless technology with wheel rim
mounted electronic sensors to monitor tire pressure
levels. Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the Re-
ceiver Module.
NOTE: It is particularly important for you to check the
tire pressure in all of the tires on your vehicle regularly
and to maintain the proper pressure. The TPMS consists of the following components:
•
Receiver Module.
• Four Tire Pressure Monitoring Sensors.
• Tire Pressure Monitoring Telltale Light.
Tire Pressure Monitoring Low Pressure Warnings
The Tire Pressure Monitoring Telltale Light will illumi-
nate in the instrument cluster, an acoustic signal will be
activated, and the “Check left or right front/rear tire”
text message will display when one or more of the four
active road tire pressures are low. Should this occur, you
should stop as soon as possible, check the inflation
pressure of each tire on your vehicle, and inflate each
tire to the vehicle’s recommended cold placard pressure
value. The system will automatically update and the
Tire Pressure Monitoring Light will extinguish once the
updated tire pressures have been received. The vehicle
may need to be driven for up to 20 minutes above
15 mph (24 km/h) to receive this information.
Check TPMS Warnings
The Tire Pressure Monitoring Telltale Light will flash on
and off for 75 seconds and remain on solid when a
system fault is detected, an audible chime will be
264 STARTING AND OPERATING

activated and the “Service Tire Pressure Monitoring
System” text message will display. If the ignition key is
cycled, this sequence will repeat providing the system
fault still exists. The Tire Pressure Monitoring Telltale
Light will turn off when the fault condition no longer
exists. A system fault can occur with any of the follow-
ing scenarios:
•Jamming due to electronic devices or driving next to
facilities emitting the same radio frequencies as the
TPM sensors.
• Installing some form of aftermarket window tinting
that affects radio wave signals.
• Snow or ice around the wheels or wheel housings.
• Using tire chains on the vehicle.
• Using wheels/tires not equipped with TPM sensors.
NOTE: Your vehicle may be equipped with a compact
spare wheel and tire assembly.
• The compact spare tire does not have a tire pressure
monitoring sensor. Therefore, the TPMS will not
monitor the tire pressure in the compact spare tire. •
If you install the compact spare tire in place of a road
tire that has a pressure below the low-pressure
warning limit, upon the next ignition key cycle, a
chime will sound and the Tire Pressure Monitoring
Telltale Light will still turn ON due to the low tire.
• However, after driving the vehicle for up to 20
minutes above 15 mph (24 km/h), the Tire Pressure
Monitoring Telltale Light will flash on and off for 75
seconds and then remain on solid.
• This occurs for each subsequent ignition key cycle, a
chime will sound and the Tire Pressure Monitoring
Telltale Light will flash on and off for 75 seconds and
then remain on solid.
• Once you repair or replace the original road tire and
reinstall it on the vehicle in place of the compact
spare tire, the TPMS will update automatically and
the Tire Pressure Monitoring Telltale Light will turn
OFF, as long as no tire pressure is below the low-
pressure warning limit in any of the four active road
tires. The vehicle may need to be driven for up to 20
minutes above 15 mph (24 km/h) in order for the
TPMS to receive this information.
